Pozanenko (IKI) report \non behalf of larger GRB follow-up collaboration:\n\nWe observed the field of GRB  111215A (Oates  et al. GCN 12681) with AZT-11 \ntelescope of CrAO observatory starting on Dec.15  (UT) 15:18:22  under mean \nseeing (FWHM) of 3.1 arsces and with Zeiss-600 telescope of Mt.Terskol \nobservatory starting on Dec.15  (UT) 21:03:45   under mean seeing (FWHM) of \n1.8 arsces . We took several frames  in R-band. Within enhanced Swift-XRT \nposition (Beardmore et al. GCN  12690) we do not detected any optical \nsource. A photometry is based on the nearby USNO-B1.0 stars (R2):\n\nT_start UT  T0+        Filter, Exposure, OT,  uplim (3 sigma)\n                  (mid, d)            (s)\n\n15:18:22  0.0738       R     21x180    n/d     21.0\n21:03:45  0.3113       R     51x60      n/d     19.3",
